Due to deemed bug in http://www.kolor.com/forum/viewtopic.php?f=19&t=26290#p162335 I suspect my libQtOpenGL.so.4 is missing because dev-qt/qtgui-4.8.6-r2 was not compiled with opengl USE flag.

What does it mean that your "libQtOpenGL.so.4 is missing"? Have you emerged dev-qt/qtopengl:4 ?
(In reply to Davide Pesavento from comment #2) > What does it mean that your "libQtOpenGL.so.4 is missing"? Thefile was not installed although dev-qt/qtgui-4.8.6-r2:4::gentoo was installed on my system. Seemed like wrong USE flags in action. > Have you emerged dev-qt/qtopengl:4 ? Yes, the very same version. As I showed, I hacked the ebuild for the version which I had previously installed ... to show the ebuild calls configure with wrong arguments. No idea why there was hardcoded "-no-opengl". Not sure the difference between use, usev and qt_use calls in my modified ebuild. But it worked for me.
libQtOpenGL is provided by qtopengl, not qtgui.
But why nothing pulled in qtopengl for me automatically? Then maybe virtual/qt could that? As of now I have: # emerge -pv qtopengl These are the packages that would be merged, in order: Calculating dependencies... done!

Ebuilds only pull in the packages they require. If you're using some third party software outside of portage, it's up to you to install the dependencies yourself.

I think such metapackages could have better desription so that I would realize they give me "reasonable" defaults. Currently it says: Cross-platform application development framework (metapackage) Hmm. :(
